Ok, this BG was robbing the bank inside WM and started shooting people. You are at the checkout right in front of the bank. You realize whats going on, make a quick accessment of your surroundings, you see no other BG's to your knowledge. You have already taken cover behind the end of the checkout stand. You draw, shoot and hit twice. He goes down but not dead. (dang 9mm) You then call 911, and there probably are others by now that have already called and possibly the bank alarm has already sent for the police. You are certain there are no other BG's. Your still on the phone with 911 and trying to calm down while trying to keep everyone around you from histeria. You're still keeping an eye on the BG and have already secured his weapon and along with store manager (probably assistant manager)(manager crapped pants and ran) are trying to keep people away. It appears secure so you holster your weapon. You're watching the front door for the police to arrive. You see a man in plain clothes coming in with a weapon drawn......... You see no badge and he's not yelling POLICE! (may not want to announce his arrival just yet, so he can possibly get an upperhand and access the situation) He could be police or could be the guys buddy that was waiting in the getaway car. Whats your next move?
